Petrobras Roncador



Landmark: Petrobras Roncador is the world’s first early-production drillpipe riser rated for 6,600 ft (2,000 m).

The Roncador Field was discovered in 1996 at water depths ranging from 4,900 to 6,600 ft (1,500 to 2,000 m) in the Campos Basin. It is 80 miles (125 km) from the coast. The Roncador field was a major breakthrough for many reasons, including the world’s first drillpipe riser, subsea tree and early-production riser (EPR) rated for 6,600 ft (2,000 m). The first well, RJS-436, produced to the FPSO Seillean from 1999 to 2001 using the EPR at a world water-depth record of 6,077 ft (1,853 m) with the GLL TLD 2000 subsea tree.

The first phase of this full-scale project was put on stream in May 2000 when the semi and FSO P-47 began operation. An accident caused P-36 to sink in March 2001, when six wells were in production. After the accident, Petrobras chartered a production unit called FPSO Brasil to temporarily substitute the P-36 platform. For a period of 5-1/2 years, eight production and three injection wells will be connected to the chartered FPSO.

In 2006, the second phase of Module IA was scheduled to begin operating 20 production wells and 10 injection wells, including those that had been connected to FPSO Brasil. These wells are tied to P-52, a brand new semisubmersible with capacity to produce 180,000 bopd. This unit is one of the largest in the world, with a total displacement of 80,000 metric tons. The feasibility studies for the other three modules of Roncador are currently under way.
